Abstract: MULTIPLE SPOKED WHEEL PRINTER       Abstract Two coaxially mounted spoked print wheels form a single printing element of a serial printer.  Each wheel contains plural spokes having print characters thereon and a selected spoke is driven by a hammer to impact paper on a platen thereby effecting printing.  Each wheel has a gap or window between two spokes of sufficient size to allow hammer or spoke entry.  In operation, the window of one wheel and the selected spoke of the other wheel are rotated to the print position.  The hammer is actuated to effect printing.  The distance between the hammer and the selected spoke is maintained constant when shifting from wheel to wheel by shifting the wheel combination axially along its axis of rotation.  The printing element is advanced relative to the platen and the platen is indexed to effect serial line printing.  The two print wheels can readily be removed as a unit from the printer and replaced for type style interchangeability.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus for maneuvering a speed-changer by operating a lever, has juxtaposedly provided therein at least two shifter forks and a mechanism for inhibiting simultaneous actuation of any plurality of the shifter forks.  The lever can selectively engage with any shifter fork.  Recesses are formed, opposed to each other, in the respective adjoining pair of the shifter forks, and a common-recess portion is provided in a region bridging over the adjoining recess bottoms.  A spring is provided for urging a tip engagement portion of the lever when all the shifter forks are in their speed-change neutral positions, to be received in the or any one common-recess portion.  When the tip engagement portion is thus received in the common-recess portion, unintentional actuation of the lever and therefore any accidential actuation of the shifter forks, is reliably inhibited even if the lever is inadvertently touched in such state.

Abstract: ABSTRACT OF THE DISCLOSURE           In the commercial production of tissue paper and the like a web, formed from a slurry of water and fiber, is creped while essentially (98%) dry, from a rotating cylindrical dryer.  Adhesives are frequently employed to hold the web to the dryer surface and acetate-ethylene copolymer emulsions serve this function.  Such adhesives are relatively soft, tend to adhere to the fabrics which carry the paper web to the dryer surface and tend to make cleaning of the carrying fabric difficult.  Additionally, these adhesives tend to cause blocking of the tissue paper when in roll form and adjacent plies of the paper tend to be torn upon separation.  However, it has been found that by providing an adhesive creping composition to have between about 10% to 33% by weight of a water soluble polyvinyl alcohol, based on acetate-ethylene copolymer solids present in the composition, the cleanability of the carrying fabric is improved, roll blocking is minimized and the consistency of the adhesion of the drying web to the dryer is improved.  Additionally, the tendency of the polyvinyl alcohol which itself has adhesive properties, to foul the dryer with a hard uneven film of alcohol is overcome.
